Exposure to the isolation and confinement of spaceflight can result in decrements in cognitive and behavioral functioning. While cognitive or behavioral conditions may not immediately or directly threaten total mission success, such conditions adversely impact individual and crew health, well-being, and performance, negatively impacting mission objectives. The rigorous astronaut selection and training processes and the […]
Risk of Acute and Chronic Carbon Dioxide Exposure
Hostile, enclosed spaceflight environments (including space vehicles and suits) do not have the benefit of natural carbon dioxide (CO2) removal. In these environments, equipment (e.g., the Carbon Dioxide Removal Assembly, lithium hydroxide, and amine systems) control CO2 levels and mitigate consequences of elevated CO2 exposure. Directed Acyclic Graph Files + DAG File Information (HSRB Home Page) […]

Concern of Venous Thromboembolism
Note: The Concern of Venous Thromboembolism is historical and now a component of CV Risk. Stagnant or reverse flow in the internal jugular vein has been observed in 6 of 11 crew members (55%) tested in-mission on approximately flight day 50; one crewmember was found to have an occlusive internal jugular vein thrombus requiring treatment […]

The NASA DC-8 Retires: Reflections on its Contributions to Earth System Science
Introduction Since 1987, a highly modified McDonnell Douglas DC-8 aircraft has been a workhorse in NASA’s Airborne Science Program (ASP)—see Photo 1. The aircraft, located at NASA’s Armstrong Flight Research Center (AFRC) in California, flew countless missions as a science laboratory, producing science data that supports projects serving the world’s scientific community, particularly the NASA […]
Summary of Special Engage Session on “Remote Sensing and the Future of Earth Observations”
Introduction On October 16, 2024, a special session of the NASA Goddard Engage series took place in the Goett Auditorium (Building 3) at NASA’s Goddard Space Flight Center (GSFC). The Engage series is intended to explain work at GSFC in an immersive and nontechnical setting. GSFC’s Office of Communications, Earth Sciences Division, and Scientific Colloquium […]
